Strange ArrayIndexOutOfBoundsException on some devices while drawing polylines

问题

Below is the code that I am using to draw routes. Whenever the user pauses the workout I want to show this path as pink polyline. I therefore made my own interface named MapHelper and taken one boolean as isPause and lastPause. When the user saves his/her workout I save all route points as array and on typical list I am displaying this maps as feeds and for that I am using lite mode version of Googlemap. Below is my adapter class

Adapter.java

public class FeedsAdpter extends RecyclerView.Adapter<FeedsAdpter.MyViewHolder> {
    private LayoutInflater inflater;
    private Context context;
    private FeedsFragment feedsFragment;
    RoundedTransFormation transFormation;
    private ArrayList<FeedsDto> allFeedsList = new ArrayList<FeedsDto>();


    public FeedsAdpter(Context context, FeedsFragment feedsFragment) {
        this.context = context;
        this.feedsFragment = feedsFragment;
        transFormation=new RoundedTransFormation(3, 15,Color.WHITE);
        inflater = LayoutInflater.from(context);
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = inflater.inflate(R.layout.item_feeds, parent, false);
        MyViewHolder holder = new MyViewHolder(view);
        return holder;
    }


    @Override
    public void onViewRecycled(MyViewHolder holder) {
        super.onViewRecycled(holder);
        if(Validator.isNotNull(holder.mapView.getMap())) {
            GoogleMap googleMap = holder.mapView.getMap();
            googleMap.clear();
            googleMap.setMapType(GoogleMap.MAP_TYPE_NONE);
        }
        Picasso.with(context).cancelRequest(holder.userImg);
        holder.userImg.setImageDrawable(null);
        holder.likeBtn.setOnClickListener(null);
        holder.commentBtn.setOnClickListener(null);
        holder.tvPost.setOnClickListener(null);

    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, int position) {
        final FeedsDto feeds = allFeedsList.get(position);
        if (Validator.isNotNull(feeds)) {


            if (Validator.isNotNull(feeds.getFeeds().getHistoryMap()) && feeds.getFeeds().getHistoryMap().length > 0) {
                if (holder.mapView != null) {
                    holder.mapView.onCreate(null);
                    holder.mapView.setVisibility(View.VISIBLE);
                    holder.mapView.getMapAsync(new OnMapReadyCallback() {
                        @Override
                        public void onMapReady(GoogleMap googleMap) {
                            if (Validator.isNotNull(googleMap)) {
                                googleMap.clear();
                                holder.mapView.setClickable(false);
                                googleMap.getUiSettings().setMapToolbarEnabled(false);
                                List<HistoryMap> historyMaps = new ArrayList<HistoryMap>();
                                historyMaps.addAll(Arrays.asList(feeds.getFeeds().getHistoryMap()));
                                Util.drawRouteIntoMap(historyMaps, googleMap);
                            }
                        }
                    });

Here is the link to json file that I'm receving Here is the link to model class that is required While drawing polylines it is throwing arrayindexoutofbound exception only in lenovo k5 among the devices I did testing on. I already asked this question on ArrayIndexOutOfBounds on Android polyline draw
